Some rules are meant to be bent — especially when it comes to style. While this doesn’t necessarily mean you should start wearing a garbage bag as a dress or your pants inside out, it doesn’t hurt to deviate a bit from the norm. For this week's Mash Photo Challenge, we partnered with Hewlett-Packard to see which rules in fashion are better bent.

Wear something new and unexpected. What are two things you thought would clash but actually complement each other perfectly, like running shoes and a dress, or denim on denim? Alternatively, repurpose an item of clothing: There are a ton of ways to wear old basics in fresh form. For example, we transformed a plaid button shirt into a stylish summer skirt.

Follow the directions below to share your photos by Sunday, July 20 at 8 p.m. ET, and we’ll feature some of our favorite submissions on our Instagram account and in a follow-up post.
